ABSTRACT
This study was conducted during 2021-22 considering various vegetable growing farmers in Unnao District (U.P.), India to find out the effect of using sewage as the only source of irrigation to their crops. In this study, 250 surface soil samples collected from farmer’s field were analyzed for Physical as well as Chemical parameters. The physical properties of soils improved due to sewage application; Bulk density ranged from 1.04 to 1.42 Mg m-3 and particle density ranged between 2.61 to 2.88 Mg m-3 and Porosity ranged between 53.4 to 61.85 with mean of 56.87 percent. Chemical Parameters such as pH, E.C., O.C., Available N, P & K were also analyzed and the results indicated that soils had a mean normal pH of 7.2, E.C. of 0.76 dSm-1, O.C. of 56.80. Available nitrogen ranged from 565 – 1217 kg ha-1 with mean of 879.56 kg ha-1.The Phosphorus availability was found ranging from 14.40 – 33.5 kg ha-1 with a mean of 23.98 kg ha-1, while Potassium was found with a mean of 205.30 kg ha-1 in range of 174 – 235 kg ha-1.
ABSTRACT
The Field experiment was carried out during rabi season of 2021-22 and 2022-23 at Students Instructional Farm, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur. The experiment consist of 14 treatments combinations in factorial randomized block design with three replications consisted of 7 fertility levels (including sulphur and zinc) and two varietal factors (i.e. Rohini & Maya). Mustard varieties Rohini & Maya were grown with the recommended agronomic practices. On the basis of results emanated from investigation it can be concluded that among the metabolic studies the maximum chlorophyll content at pre and post anthesis are 46.70 and 48.88 SPAD were recorded in the treatment T14 [Var. Maya with Sulphur @900 ppm] during the first year (2021-22). Maximum rate of photosynthesis at pre and post anthesis are 25.97 and 33.29 µmole m-2/ s-1 respectively, during 1st years of experimentation were associated with the treatment T14 [Var. Maya with Sulphur @900 ppm]. Similarly during 2nd year of experimentation the maximum pre and post anthesis chlorophyll content (47.27 and 49.45 SPAD) and pre and post anthesis rate of photosynthesis (26.32 and 34.50 µmole m-2/ s-1) was found in the treatment T14 [Var. Maya with Sulphur @900 ppm]. Along with this, among the phenological studies minimum number of days taken to anthesis, number of days taken to 50 % flowering and number of days taken to maturity, was also found in the treatment T14 [Var. Maya with Sulphur @900 ppm].
ABSTRACT
An investigation was carried out during 2021-22 at various land use planning of Kanpur Nagar (U.P.) to evaluate the availability of nutrients effect of various land use planning on soil. The 504 representative soil samples with 3 depths viz. 0-15, 15-30, and 30-60 cm soil samples were taken with manually driven post hole auger and processed for soil analysis from different land use planning of Kanpur Nagar. Available nitrogen, phosphorus, potassium, Sulphur, micro nutrients (Fe, Cu, Mn and Zn) and notable available Nitrogen in different lands low in ranged from 112.4 – 199.3 kg ha-1. The Phosphorus availability was found in ranged from 8.40 - 19.90 kg ha-1, while Potassium was found in ranged from 111.30 - 192.10 kg ha-1. However the availability of Sulphur, was found in ranged from 7.40 - 23.80 mg kg-1 and the availability of micro nutrients like - available Iron ranged from 4.34- 16.9 mg kg-1, available Manganese ranged from 1.10- 10.9 mg kg-1, available Copper ranged from 0.47 – 3.76 mg kg-1, and available Zinc ranged from 0.33- 2.54 mg kg-1.
